Thanks again for opening this ticket @lifeart. After some digging, I believe I've found the issue.

ember-language-server/src/template-linter.ts

Lines 154 to 155 in 0c27ced

	const linterMeta = project.dependenciesMeta.find((dep) => dep.name === 'ember-template-lint');
	const linterVersion = linterMeta?.version.split('.')[0] || 'unknown';

Description

Here the version checking doesn't allow for any of the preceding characters of semver, so if you have a ~ or or a ^ preceding the version number it is read incorrectly.

Which then gets consumed here:

ember-language-server/src/template-linter.ts

Lines 102 to 104 in 0c27ced

	if (templateLintVersion === '5') {
	return [documentContent];
	}

I downgraded ember-template-lint to 5, and then pinned it to the version explicitly (removing the preceding character) which works around the issue for now.
